The time (X) to complete a standardized exam is approximately normal with a mean of 70 minutes and standard deviation of 10 minu
notka56 [123]

Answer:

77.88 minutes

Step-by-step explanation:

Given that :

Mean (m) = 70

Standard deviation (s) = 10

For 80% of student to complete the exam. In the given time

Using the formula :

Zscore = (X - mean) / standard deviation

80th percentile = 80/100 = 0.8 has a Zscore = 0.7881

0.7881 = (X - 70) /10

0.7881 * 10 = X - 70

7.881 = X - 70

7.881 + 70 = X

77.881 = X

Hence, 77.88 minutes should be given

What must be true of two rational expressions before they can be added?
VladimirAG [237]

Answer:

They most have common denominators.

Step-by-step explanation:

Let the following two rational expressions:

\frac{p}{a}  , \frac{q}{b}

where p,a,q, b are integers, a and b the denominators are not 0, i.e. a,b\neq 0

We can add rational expressions only if their denominator is same.

That is why we find LCD to be ab.

Then,

\frac{p}{a} +\frac{q}{b} =\frac{pb+qa}{ab}

Let the following two rational expressions:

\frac{p}{a}  , \frac{q}{b}

where p,a,q, b are integers, a and b the denominators are not 0, i.e. a,b\neq 0

We can add rational expressions only if their denominator is same.

That is why we find LCD to be ab.

Then,

\frac{p}{a} +\frac{q}{b} =\frac{pb+qa}{ab}

So, the correct answer is the last option that we can sum rational expressions if they have common denominator.
